Answer:
the value of line ST is 6 centimeters long
Step-by-step explanation:
The attached image in conjunction with the question is shown in the file below.
We can see from the RT segment that the equation given can be expressed as:
so; if we solve for x ; we have ;
divide both sides by 5 ; we have:
However ; the value of ST is represent by the information:
replcaing the value for x; we have :
Thus, the value of line ST is 6 centimeters long
Using the inverse function concept, the table that represents the inverse of the table given is table a.
<h3>How to find the inverse of a function of pairs (x,y)?</h3>
The inverse of the function is given by the set that contains point (y,x), that is, the coordinates are exchanged.
In the table given, we have points (0,0), (2,1) and (4,2), hence the inverse table has points (0,0), (1,2) and (2,4), which is table a.

(-13/2,3), use formula x2+x1/2,y2+y1/2
Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
To find how much the temperature fell we must find the difference of both numbers and to do this we subtract them;
20 - (-5) = 25 degrees
